PACKING FOR EGGS AND OTHER FBAGILE ARTICLES.

Application filed July 18, 1922. Serial No. 575,807.

To all whbm it may concern:

Be it known that we, LEON MANN and MORRIS KOPPELMAN, citizens of theUnited States, and residents, respectively, of the city of Mount Vernon,in the county of Westchester, State of New York, and the borough ofBrooklyn, in the county of Kings, city and State of New York, haveinvented certain new and useful Improvements in Packings for Eggs andOther Fragile Articles, of which the following is a specification.

The improvements relate to the packing of fragile articles, such aseggs, electric light and other glass bulbs, and similar articles, andtheir primary ob'ects are the production of a packing unit a apted to beused with the standard or other cell-forming fillers, and to secure andhold the packing units as well as the articles therein and protect thelatter from injury.

We have found that the cracking and breaking of eggs and like articles,when packed in cases or other containers employed for transportation andstorage, is due chiefly to two causes, viz: the movement of the articlesin the packing, and to the movement of the packing elements relat ing toeach other thereby subjecting the said articles to cracking or breakingshocks or strains. Various means have been devised for protecting thearticles, but for many reasons the standard filler or cell-formingelement and flats interposed between the layers of fillers are almostuniversally used. The present improvements are adapted to be used withthe standard flats and fillers, or with flats or fillers of othercharacter, and not only holding the articles themselves 40 but secure orlook them in their proper positions relative to each other.

The improvements are illustrated in the accompanying drawings, in whichFigure 1 is a transverse vertical section, through the egg-holding andfiller locking projections showing two flats and. interposed fillermembers, and Fig. 2 is a plan of the same construction.

In carrying out the present improvements the flats 1 are provided with aseries of knobs or studs 2, so disposed and distributed that one islocated in each corner of each e g-receivin compartment of the filler 4,w on the f il er is in place. These are pref erably conical in form, asshown, and made integral with the flat, which we make of felted woodpulp or other fprefer to bres, the

form and arrangement of these projections,

however, may bevaried within certain limits without departing from thescope of the present improvements, and they may be made in anysatisfactory manner and of any suitable material.

The flat with the may therefore be arranged so that the said articledoes not normally rest thereon.

is desirable nevertheless in most cases to have them so formed andpositioned that they will form cushions or stops in the corners of thecells.

The filler 4 may be of standard form and may consist of the usualstraw-board strips intersecting one another at right angles, but theusefulness of the present improvements is not limited to this particularform. The lower edges of the filler or cell-forming strips fit inbetween the rows of projections and rest upon the narrow strip 6 of theflat or bottom portion, and in the illustration shown are held againstmovement parallel or at right angles to the said strips, and alsoagainst diagonal movement to any material extent thereby. It istherefore advisable to so locate the projections that they 00- cupy thecorners formed by the intersection of the strips.

In use a flat is first placed in the bottom of a with their inner sidesurfaces 3 and 8, while the medial portion 9 of the said article extendsbeyond the said surfaces, above them, and in proximity to the walls ofthe cell.

The. filler may then be laced in position,

its lower edgesbeing guided to the bottom grojections of the narrowspace between the by the inclined sides 7 thereof,

f desired,

however, the filler may be placed in position first and the articlesdropped or placed therein. Dotted lines in Fig. 2 indicate the positionof the lower portion and the medial portion respectively of the articlewhen in osition. Another fiat is then placed on the filler, covering thecells, and the operation repeated until the desired number of layershave been packed.

One of the advanta es of the resent form is that a flat may rst be paced in the bottom of the case in inverted position or in normalposition with a sheet of strawboard or other material interposed betweenit and the first holding flat, and the same thing may be done at the toof the container, to form an extra cus ion. It will also be apparentthat the flats at the top of the fillers may be inverted, so that eachfiller will have four of the knobs or projections at both top andbottom. This looks the fillers at top and bottom and also providesholders for the articles in the cells at both ends. It has been foundhowever that with most articles the location of the projections in thebottom only is sufficient for all ordinary purposes.

In order to enable those skilled in the art to fully realize theadvantages of the improvements it is pointed out that two pro jectionsmay be used instead of four, as shown at the center of Fig. 2, thesebeing arranged in diagonally opposed corners of the rectangles formed bythe filler members 4. In this manner the fillers and flats may beeffectively locked, and if desired, other means may be employed forholding and supporting the article. On the other hand the number ofprojections may be increased, and each group or set may consist of acluster of more than four, or the groups may he in efi'ect double rows.Various other modifications within the scope of the improvements willsuggest themselves to those skilled in the art.

What we claim is:

1. In a packing of the type including flats and collapsible cell-formingfillers, a flat comprising a sheet havin bulged areas formed therein,said bulge areas being so disposed as to revent lateral movement of thecell Walls o the engaged filler.

2. In a packing of the type including flats and collapsible cell-formingfillers, a flat comprising a sheet having protuberances formed thereinwithout severing the material, said rounded protuberances being sodisposed as to prevent lateral movement of the cell walls of the engagedfiller.

3. A packing of the character described, comprising a sheet of materialprovided with spaced projections and upright members placed thereon toform compartments for receiving the articles to be packed, hav ing theirlower portions between said projections, a plurality of said projectionsbeing located in each compartment at one end thereof and adjacent to thesaid members and having locking relation therewith, the said projectionsbeing spaced apart and constructed and arranged to receive the lowerpart of the article to be packed and to hold and support the same.

4. The combination of a sheet of material provided with spacedprojections thereon, the said projections being arranged in groups orsets of two or more, and the groups being spaced apart a suflicientdistance to permit the article to be packed to be inserted therebetween,upright members extending laterally on lines angular to each other,forming compartments and extending between members of said groups, separating them and bein held thereby against lateral movement in a 1directions.

5. The combination of a sheet of material provided with spaced conicalprojections thereon, the said projections being arranged in groups orsets of two or more, and the groups being spaced apart a sufficientdistance to permit the article to be packed to be insertedtlicrebetween, upright members extending laterally on lines angular toeach other, forming compartments and extending between members of saidroups, separating them and being held there y against lateral movementin all directions.

6. In a packin of the type including Hats and collapsi 1e cell-formingfillers, a flat comprising a sheet having rounded protuberances formedtherein, said rounded protuberances being so disposed as to preventlateral collapse of the cell walls of the engaged filler, and saidrounded protuberances being adapted to support a packed article out ofcontact with the walls of the containing cell.

Witness our hands this 17th day of July, 1922, at the cit of New. York,in the county and State of ew York.
